How to use Pushbuttons with Arduino. Pull up vs Pull down resistors

Here is the video covering the topic of Pull up and Pull down resistore. As you would learn from it two years ago this topic was quite new to me.
At that time I could not find a comprehensive or clear enough video covering that topic. So I decided to make one myself:)
Hope you find it usefull.
